Definitions

• the present invention relates in the field of tools, more precisely applied to tools for dental and orthopedic implants (medical indication) with magnetic force.
• Ratchet-type keys are essential tools for ergonomics and agility and can be used in several areas. With them, injuries can be avoided by both effort and impact, because these tools allow the user to tighten a screw or nut repeatedly without always repositioning the tool, since the inner ratchet keeps the socket in place while the key arm is repositioned.
• silicone o'rings with the ratchet wrench to promote the mechanical retention of a second wrench.
• this measure avoids direct contact of the user/professional with the key/instrument that will contact the patient's body during the surgical procedure.
• instruments of this nature need to be sterilized before each use.
• silicone rings they are expected to gradually lose their properties due to the effect of high temperature during autoclaving process, so that they no longer firmly retain the insertion key.
• metal rings also lose their spring effect properties in view of natural wear related to time of use.
• patent document BR 10 2013 008127 2 describes a linear or rotational motion mechanism with magnetic memory retention. More specifically it comprises a mechanism for switching position and maintaining the position by the attraction between a magnet and a ferromagnetic core, with electricity consumption only during the switching of the position.
• the invention provides a linear or rotational motion mechanism with magnetic memory retention that only uses electrical energy to switch between the two positions and once one of the positions is established, there is no longer a need for electrical energy to maintain the position.
• Document PI 0710446-4 describes a cylinder lock protection system that, when a magnet lock unlocks in response to a magnet approach, such a lock is unlocked. Thus, it can be switched between a state in which the insertion of a mechanical wrench into the key hole of an internal cylinder with pivotal rotation supported in a cylinder body is allowed and a state, and another in which the insertion of the mechanical key into the key hole is prevented, so that a shutter mechanism is arranged in the cylinder body, the shutter mechanism having a pivotal rotation member and a shutter plate, the pivoting limb having an insertion hole to allow the insertion of the mechanical key into the key hole and pivotal rotation around the same axis.
• the pivot axis of the inner cylinder can be moved in response to a pivoting operation when the magnet lock is unlocked and the shutter plate being operated to the pivoting limb so as to move between an open position in which the insertion hole is opened and a closed position in which the insertion hole is fully closed in response to pivoting of the pivoting limb.
• the magnet is provided in a key box that attaches prominently with the pivoting member and is able to pivot the pivot member in the united state, the magnet enabling the magnet lock to be unlocked in a state where the key box is attached with the pivoting member, in which the key box retracts the mechanical key, so that the mechanical key is made to project itself from the key box and be inserted into the key hole in a state in which the pivoting limb is pivoted, so as to place the shutter plate in the open position, and a coupling part is provided on the cylinder body side , the coupling part preventing the key box from becoming detached from the pivoting limb by coupling with the key box when the mechanical key is made to protrude from the key box at least after the magnet latch is unlocked and the shutter plate is placed in the open position.
• Document MU9000900-2 refers to a construction arrangement introduced in rapid coupling acting by magnetic action and which is intended for the retention of shelf supports in bushings fixed to vertical panels, partitions, furniture or walls, in particular for display of goods.
• the proposed coupling comprises a rod that penetrates inside a bushing, which is fixed to the vertical panel, whose movement is rectilinear, without inclinations or rotations.
• the rod has any prismatic end, optionally heist, that penetrates into an inner chamber of the bushing with the same cross section, whose bottom has a magnet that retains the rod.
• the bushing has a protruding edge and an outer thread that receives a fastening nut on the vertical panel.
• the bushing attachment nut on the panel may also have a protruding edge.
• both the protruding edge of the bushing and the nut can feature a peripheral groove that houses an o- ring for better grip on the panel surface.
• the document CN201879855 belongs to the technical field of medical device, in particular a magnetic retainer for teeth, which uses a permanent magnet of neodymium-iron-boron of rare earths to generate a strong magnetic attraction force and is used for the retention of the dental prosthesis.
• the present invention achieves this and other objectives through an instrument of medical/dental insertion, the instrument comprising: an axle; a fixing region; and an insertion element; where the fixing region makes the connection of the insertion element and the axle; the axle rotating the insertion element when connected; wherein the fixing region comprises a magnet configured to fix the insertion element on the axle.
• the fastening region comprises at least one hole in a position perpendicular to the axle, wherein the magnet is inserted into the hole in order to fix the insertion element on the axle, and the magnet is preferably manufactured in samarium, cobalt or neodymium, and may comprise an external layer of moisture-resistant protection.
• the insertion element is configured to connect to a medical/dental device, where the shaft is manufactured in Stainless Steel according to ASTM F-899, the length of the medical/dental insertion instrument varies between 16 mm and 250 mm, preferably from 16 mm to 40 mm for dental applications and between 150 mm and 250 mm for orthopedic keys and the magnet fitting hole has a width between 2.0 mm and 8.00 mm.
• the present invention also describes a dental insertion tool, comprising a medical/dental insertion instrument according to the above defined, in which the tool is of the type against angle and/or ratchet.
• a dental insertion tool comprising a medical/dental insertion instrument according to the above defined, in which the tool is of the type against angle and/or ratchet.

• Figs. 1 and 2 present invention describes an instrument of medical/dental insertion, the instrument comprising: an axle 1 ; a fixing region 2; and an insertion element 4; where the fixing region 2 makes the connection of the insertion element 4 and the axle 1 ; the axle 1 rotating the insertion element 4 when connected; where the fixing region 2 comprises a magnet 3 configured to fix the insertion element 4 on axle 1 . [0026].
• the fixing region 2 comprises at least one hole 3' in a position perpendicular to axle 1 , wherein the magnet 3 is inserted into hole 3' in order to fix the insertion element 4 on axle 1 , and magnet 3 is preferably manufactured in samarium, cobalt or neodymium, and may comprise an external layer of humidity-resistant protection, as shown in the cut-view of Fig. 3.
• the insertion element 4 is configured to connect to a medical/dental device, where shaft 1 is manufactured in Stainless Steel according to ASTM F-899, the length of the dental and medical insertion instrument varies between 16 mm and 250 mm, and the 3' hole for magnet fitting 3 comprises a width between 2.0 mm and 8.0 mm.
• the 3' hole can receive a cover 6 on both sides, which prevents the magnet from being exposed to the environment or humidity at the time of autoclaving, preventing the magnet from being corroded.
• the cover 6 can be made of resin or polymers, so as to seal the hole 3' with the magnet inside, being ideal for autoclave sterilization processes.
• the present invention also describes a tool 5 of dental and medical insertion, comprising an instrument of dental and medical insertion according to the above defined, in which tool 5 is of the type against angle and / or ratchet, as shown in Fig. 4.

• axle 1 is tightly fitted to the tool 5, as shown in figure 4.
• the same torque is applied to axis 1 , which in turn transmits the torque to the insert 4, which finally transmits the torque to the implant or prosthesis screw.
• Another advantage is the durability of its components, which are exposed multiple times to processes such as autoclave.
